trolled engine performance system.
WARNING
EWA18440
Do not change the d rive mo de while
the vehicle is movin g.The “D-MODE” system consists of 4
different control maps which regulate
engine response and output, thus pro-
viding you with a selection of modes to
fit your preferences and the riding envi-
ronment.
D-MODE 1 - Sporty engine response
D-MODE 2 - Moderate engine re-
sponse
D-MODE 3 - Mild engine response
D-MODE 4 - Mild engine response and
limits engine outputTIP The current “D-MODE” setting is
shown in the MODE display. (See
page 4-11.)
 The current “D-MODE” setting is
saved when the vehicle is turned
off. 
The “D-MODE” is controlled by
the MODE switches, see page 4-4
for more information.

“TCS-MODE”This model is equipped with adjustable
traction, slide, and lift control systems
(TCS, SCS and LIF). These are
grouped together into “TCS-MODE”.
“TCS-MODE” has 4 settings:
“TCS-MODE M” is customizable in the
settings MENU, see page 4-15.
TCS
The traction control system helps
maintain traction when accelerating. If
sensors detect that the rear wheel is
starting to slip (uncontrolled spinning),
the traction control system assists by
regulating engine power as needed un-
til traction is restored. The stability
control indicator light “ ” flashes to
let the rider know that traction control
has engaged.

This traction control system automati-
cally adjusts according to the vehicle’s
lean angle. To maximize acceleration,
when the vehicle is upright a lesser
amount of traction control is applied.
When cornering, a greater amount of
traction control is applied.
TIP
The traction control system may
engage when the vehicle travels
over a bump.
 You may notice slight changes in
engine and exhaust sounds when
the traction control or other sys-
tems engage.
 The traction control system can
only be turned off by setting “TCS-
MODE” to “OFF”, using the MODE switches. See page 4-4 for more
information on “TCS-MODE”.
 When “TCS-MODE” has been set
to “OFF”, the TCS, SCS and LIF
systems are all turned off togeth-
er.

tires will prevent the traction control
system from controllin g tire rotation
accurately.SCS
The slide control system regulates en-
gine power output when a sideward
slide is detected in the rear wheel. It
adjusts power output based on data
from the IMU (Inertial Measurement
Unit). This system supports the TCS to
contribute to a smoother ride.
LIF
The lift control system reduces the rate
at which the front wheel rises during
extreme acceleration, such as during
starts or out-of-corner exits. When
front-wheel lift is detected, engine

BCThe brake control system regulates hy-
draulic brake pressure for the front and
rear wheels when the brakes are ap-
plied and wheel lock is detected. This
system has two settings.
BC1 is standard ABS, which adjusts
brake pressure based on vehicle
speed and wheel speed data. BC1 is
designed to engage and maximize
braking when the vehicle is upright.
BC2 uses additional data from the IMU
to regulate applied brake power when
cornering to suppress lateral wheel
slip.
WARNING
EWA20891
The brake control system is not a
su bstitute for the use of proper ri d-
in g an d brakin g techniques. The

“Manual TCS Settin
g”
This module allows you to customize
the “TCS-MODE M” which is accessi-
ble on the main display using the
MODE switches.
TCS
This model uses a variable traction
control system. For each setting level,
the further the vehicle is leaned over,
the greater the amount of traction con-
trol (system intervention) is applied.
There are 3 setting levels available for
the “TCS-MODE M”. Setting level 1 applies the least amount
of overall system intervention, while
setting level 3 applies the greatest
amount of overall traction control.
TIP
TCS can only be turned on or off
via the main screen using the
MODE switches.
 SCS and LIF can be turned off in-
dependently of TCS for “TCS-
MODE M”.
 When “TCS-MODE” has been set
to “OFF” on the main screen: TCS,
SCS and LIF are all turned off to-
gether.SCSSCS can be set to OFF, 1, 2, and 3.
OFF turns the slide control system off,
setting level 1 provides the least
amount of system intervention, and
setting level 3 provides the greatest
amount of system intervention.
LIFLIF can be set to OFF, 1, 2, and 3. Setting level 1 provides the least
amount of system intervention and set-
ting 3 most strongly reduces the rate of
wheel lift.
OFF turns LIF off.

Brake control system (BC)The brake control system regulates hy-
draulic brake pressure for the front and
rear wheels independently when the
brakes are applied and wheel lock is
detected. This system has two settings
which can be changed in the settings
MENU. (See page 4-15.)
BC1 is standard ABS, which adjusts
brake pressure based on vehicle
speed and wheel speed data. BC1 is
designed to engage and maximize
braking when the vehicle is upright.
BC2 uses additional data from the IMU
to regulate applied brake power when
cornering to suppress lateral wheel
slip.
Regarding ABS, operate the brakes as
you would conventional brakes. When
the brake control system engages, a
pulsating sensation may be felt at the
brake lever or brake pedal as the hy-
draulic unit rapidly applies and reduces
brake pressure. In this situation, conti-
nue to apply the brake lever and brake
pedal to allow the ABS to work—do
not “pump the brakes” as this will re-
duce braking effectiveness.
WARNING
EWA16051
Always keep a sufficient d istance
from the vehicle ahead to match the
ri din g speed even with ABS.
 The ABS performs best with
lon g b rakin g d istances.
 On certain surfaces, such as
rou gh or g ravel roa ds, the b rak-
in g d istance may be lon ger with
the ABS than without.The ABS hydraulic unit is monitored by
the ABS ECU, which will revert the sys-
tem to conventional braking if a mal-
function occurs.
WARNING
EWA20891
The brake control system is not a
su bstitute for the use of proper ri d-
in g an d brakin g techniques. The
b rake control system cannot pre-
vent all loss of traction due to over-
b rakin g from excessive spee d, or
lateral wheel slip when brakin g on
slippery surfaces.
TIPThe ABS performs a self-diagnostic
test when the vehicle is started and
reaches a speed of 5 km/h (3 mi/h).
During this test, a clicking noise may
be audible from the hydraulic control
unit, and a vibration may be felt at the
brake lever or pedal, but this is normal.NOTICE
ECA20100
Be careful not to d amage the wheel
sensor or wheel sensor rotor; other-
wise, improper performance of the
ABS will result.1. Front wheel sensor rotor

6 4. After starting out, close the throt-
tle, and at the same time, quickly
pull the clutch lever in.
5. Shift the transmission into second gear. (Make sure not to shift the
transmission into the neutral posi-
tion.)
6. Open the throttle part way and gradually release the clutch lever.
7. Follow the same procedure when shifting to the next higher gear.
EAU85380
To decelerate
1. Release the throttle and apply both the front and the rear brakes
smoothly to slow the motorcycle.
2. As the vehicle decelerates, shift to a lower gear.
3. When the engine is about to stall or runs roughly, pull the clutch le-
ver in, use the brakes to slow the
motorcycle, and continue to
downshift as necessary.
4. Once the motorcycle has stopped, the transmission can be
shifted into the neutral position. The neutral indicator light should
come on and then the clutch lever
can be released.
WARNING
EWA17380

Improper brakin g can cause
loss of control or traction. Al-
ways use b oth brakes an d apply
them smoothly.
 Make sure that the motorcycle
and the en gine have sufficiently
slowe d b efore shiftin g to a low-
er gear. En gag in g a lower gear
when the vehicle or en gine
speed is too hi gh coul d make
the rear wheel lose traction or

Tips for re ducin g fuel con-
sumptionFuel consumption depends largely on
your riding style. Consider the follow-
ing tips to reduce fuel consumption:
 Shift up swiftly, and avoid high en-
gine speeds during acceleration.
 Do not rev the engine while shift-
ing down, and avoid high engine
speeds with no load on the en-
gine.
 Turn the engine off instead of let-
ting it idle for an extended length
of time (e.g., in traffic jams, at traf-
fic lights or at railroad crossings).
